CHARLES PHELPS, OF OSKALOOSA, IOWA.

SHEET-METAL RADIATOR.

SPECIFICATION forming part of Letters Patent No. 689,986, dated December 31, 1901.

Application filed July 28, 1900. Serial No. 25,115. (No model To all whom it may concern.-

Be it known that 1, CHARLES PHELPS, a citizen of the United States, residing at Oskaloosa, in the county of Mahaska and State of Iowa, have invented certain new and useful Improvements in Sheetdvletal Radiators, of which the following is a specification.

The object of my invention is to provide improved means of simple, durable, and inexpensive construction whereby the sheetmetal sides are internally braced atthe point where connection is made between the radiator-sections, and at the same time a firm support is provided to receive push-nipples or other means for connecting two or more sections.

More specifically, my object is to provide a brace of the character described made of three pieces, two of which are smooth annular rings and the other an annular collar having openings cast or otherwise formed in its edges to provide for the circulation of steam or hot Water from the interior of the collar into the radiator-section and at the same time to provide means whereby the inner collar is prevented from moving relative to the rings, thus attaining all of the advantages of a one-piece collar having circulating-openings through its central peripheral portion and avoiding the expense of coring said openings when the collar is made of cast metal or of boring openings when made otherwise.

My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 shows in side elevation the central collar having notched edges with one of the smooth rings abutting against one end of the collar and the remaining ring illustrated in perspective adjacent to the opposite end of the collar. Fig. 2 shows a modification of the central collar in which the collar is made of a single piece of wire. Fig. 3 shows another modification of the central collar in which a collar is made from a single piece of plate metal that may be formed by dies. Fig. 4 shows a vertical central sectional view of the lower end portion of a sheet-metal radiator having my improved brace therein and showing a push-nipple in one end of the brace. Fig. 5 shows a detail vertical sectional View illustrating a modified form of device for preventing a vertical movement of the collar relative to the rings.

Referring to the accompanying drawings, I have used the referencanumeral.10 to indicate that portion of a sheet-metal radiator shown. Near the base of the radiator and in both sides is an outwardly-projecting annular rim 11 to surround the opening 12, into which the push-nipples 13 or other means for connecting two or more radiator-sections together is placed. The central collar is indicated by the reference-numeral l4 and is preferably cast with circulating openings or notches 15 in both ends. On each end of the part 14 I have formed one or more outwardlyprojecting pins 16. The rings indicated by the reference-numeral 17 are of the same diameter as the collar 14 and are smooth on their outer faces, and each ring is provided with an opening 18 on its inner face to admit the projections 16. By this means it is obvious that the expense of coring holes in the collar 14 when made of cast metal is avoided and the expense of boring holes when otherwise made is also avoided, and at the same time the parts are held together in a manner to accomplish the purpose for which they are intended as well as though the entire brace were made of one piece.

In the modification illustrated in Fig. 2 have shown a collar made of a single piece of wire. This collar is indicated by the numeral 19, and the wire is doubled upon itself, with spaces between the folds, and is then bent into cylindrical shape. At each end of the collar thus formed one or more of the folds of wire are projected beyond the collar proper at 20, and these projecting portions are designed to enter into the openings 18 in the rings 17.

In the modification shown in Fig. 3 I have shown a collar that may be formed from a piece of sheet or plate metal by dies. The edges of the sheet of metal 21 are notched at 22,and then the part is formed into cylindrical shape, as clearly shown in the figure. On each end of the collar thus formed one or more projections 23 are formed, designed to enter the openings 18 of the rings 17 for the same purpose as before described in connection with the projections 16.

Each of the modified forms of collars shown in Figs. 2 and 3 is designed to take the place of and be used in exactly the same manner as the collar 14:, shown in Fig. 1, and the same rings 17, having openings 18, are used in connection with each of said collars in providing a complete brace.

In the modified form shown in Fig. 5 I have Y provided a different means for preventing the inner collar 14 from moving within the radiator-section,as follows: The rings 17 are made of such thickness and the shoulders 11 are made of such depth that the ends of the collar 14 will enter said shoulders, and thereby be prevented from moving upwardly or down- Wardly within the radiator-section.

It is obvious that with either of the forms shown the two rings may be placed in the annular shoulders 11 before the sides of the sheet-metal radiator are brought together, and the inner collar may be connected with one side, so as to be temporarily supported therein until the sides of the section are brought together. This will be so whether the means for connecting the central collar is the same as illustrated in Figs. 1, 2, and 3 or that illustrated in Fig. 5.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States therefor, is

1.. In a radiator the combination of a radiator-section provided with openings in its sides, of a brace situated Within said section and surrounding said openings the said brace comprising a collar formed with notches in its edges, and rings engaging the outer edges of said collar,said collar being supported against displacement when the parts are assembled.

2. The combination with a sheet-metal radiator section having openings in its sides, through which communication is bad between adjacent sections, and also having annular shoulders formed on its sides to project outwardly around said openings, of two rings on the interior of the radiator-section, one to lie on each of said annular shoulders, said rings being of such thickness that the annular shoulders will project inwardly beyond the inner faces of the rings, and a central collar having notched edges placed between the rings and in engagement therewith, for the purposes stated.
